Warning. always turn OFF the gas supply at the gas service cock, and switch OFF and disconnect the electricity<br />
supply to the appliance before servicing.<br />
Combustion testing must be carried out by a competent person using a combustion analyser conforming to Bs7927.<br />
To ensure the continued safe and efficient operation of the appliance it is recommended that it is checked at regular intervals and<br />
serviced as necessary. The frequency of servicing will depend upon the installation condition and usage but should be carried out<br />
at least annually.<br />
It is the law that any service work must be carried out by a Gas Safe Registered Engineer. In IE service work must be carried out<br />
by a Registered Gas Installer (RGII).<br />
INspECTION<br />
1. Light the boiler and carry out a pre-service check, noting any<br />
operational faults.<br />
2. Check the flue terminal (and terminal guard if fitted) is undamaged<br />
and clear of any obstruction.<br />
3. Check all water and gas joints for signs of leakage. Remake any<br />
suspect joints ensuring a gas tightness check is carried out if<br />
applicable and the water system is correctly refilled, vented and<br />
re-pressurised.<br />
CLEaNINg pROCEDURE<br />
Note. In order to carry out either servicing or replacement of<br />
components the boiler front panel must be removed. Refer to<br />
Frame 39.<br />
1. Clean the main burner. Refer to frame 41.<br />
2. Clean the heat exchanger & condensate trap/siphon. Refer to<br />
Frames 42 & 43.<br />
3. Check the main injector for blockage or damage. Refer to Frame<br />
40.<br />
4. Check that the flue terminal is unobstructed and that the flue system<br />
is sealed correctly.<br />
ALSO IF THE DHW FLOW RATE IS IN QUESTION :-<br />
5. Check the DHW filter for blockage. Refer to Frame 69.<br />
The cleaning procedures are covered more fully in Frames 39-44 and<br />
MUST be carried out in sequence.<br />
IMpORTaNT.<br />
6. After completing the servicing or exchange of components always<br />
test for gas tightness.<br />
7. When work is complete the front panel MUST be correctly refitted,<br />
ensuring that a good seal is made.<br />
Do noT operaTe the boiler if the front panel is not<br />
fitted.<br />
8. If, for any reason, the condensate trap/siphon has been removed<br />
ensure the trap is refilled with water before<br />
reassembling.<br />
9. Check the gas consumption.<br />
10. Check combustion by connecting the flue gas analyser to the flue<br />
gas sampling point as shown in the diagram and measure CO &<br />
CO . 2<br />
If the CO/CO 2 ratio is greater than 0.004 AND the integrity of the<br />
complete flue system and combustion circuit seals have been<br />
verified and the inlet gas pressure (and gas rate) have been<br />
verified, then contact Wolseley Centers Ltd.<br />
11. Complete the service section in the Benchmark Commissioning<br />
Checklist.<br />
gENERaL<br />
please note: During routine servicing, and after any<br />
maintenance or change of part of the combustion<br />
circuit, the following must be checked:<br />
- The integrity of the flue system and the flue seals,<br />
- The integrity of the boiler combustion circuit and<br />
the relevant seals<br />
- The operational (working) gas inlet pressure at<br />
maximum rate.<br />
- The gas rate<br />
- The combustion performance.<br />
COMpETENCE TO CaRRy OUT ThE ChECK<br />
OF COMBUsTION pERFORMaNCE<br />
please note: BS 6798:2009 Specification for<br />
installation and maintenance of gas-fired boilers of<br />
rated input not exceeding 70kW net advises that:<br />
- The person carrying out a combustion<br />
measurement should have been assessed as<br />
competent in the use of a flue gas analyser and the<br />
interpretation of the results.<br />
- The flue gas analyser used should be one meeting<br />
the requirements of BS7927 or BS-EN50379-3<br />
and be calibrated in accordance with the analyser<br />
manufacturers requirements, and<br />
- Competence can be demonstrated by satisfactory<br />
completion of the CPA1 ACS assessment, which<br />
covers the use of electronic portable combustion<br />
gas analysers in accordance with BS7967, Parts 1<br />
to 4.<br />
